Abstract
Molecular wires containing p-phenylene sulfide units were synthesized. They could be used in material sciences and in supramolecular chemistry. Wires having 2 to 6 phenyl rings were functionalized at one end by an SH or SMe group, and at the other end, by an OH, OMe or OiPr groups. Formation of ArS bonds in the chain was achieved by Pd- or Cu-catalyzed couplings of aromatic thiols with aromatic halides. Conditions for a clean chemoselective deprotection of thiols from thiomethyl groups were developed.
